Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
mot trieu » mot chieu, mot tri, mon triet
trung cam » trung tam, trung cap, trung nam
bang cong » dang cong, bang song, hang cong
khan cap » than cap, khoan cam, phan cac
khan ap » han ap, khan dam

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: mot trieu tinh - thanh trung cam ((nhung cong) OR (bang cong)) san ((khan cap) OR (khan ap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "mot trieu tinh - thanh trung cam ((nhung cong) or (bang cong)) san ((khan cap) OR (khan ap))~".
• Adding a wildcard symbol may retrieve word variants: mot trieu tinh - thanh trung cam ((nhung cong) or (bang cong)) san ((khan cap) OR (khan ap))*.
